Evolving division of labor in a response threshold model
José F. Fontanari, Viviane M. de Oliveira, Paulo R. A. Campos
The response threshold model explains the emergence of division of labor (i.e., task specialization) in an unstructured population by assuming that the individuals have different p…
Predictability of the imitative learning trajectories
Paulo R. A. Campos, José F. Fontanari
The fitness landscape metaphor plays a central role on the modeling of optimizing principles in many research fields, ranging from evolutionary biology, where it was first introduc…
The influence of the composition of tradeoffs on the generation of differentiated cells
André Amado, Paulo R. A. Campos
We study the emergence of cell differentiation under the assumption of the existence of a given number of tradeoffs between genes encoding different functions. In the model the via…
Coexistence of competing metabolic pathways in well-mixed populations
Lenin Fernández, André Amado, Fernando Fagundes Ferreira +1
Understanding why strains with different metabolic pathways that compete for a single limiting resource coexist is a challenging issue within a theoretical perspective. Previous in…
Excitable Scale Free Networks
Mauro Copelli, Paulo R. A. Campos
When a simple excitable system is continuously stimulated by a Poissonian external source, the response function (mean activity versus stimulus rate) generally shows a linear satur…
Bounded fitness landscapes and the evolution of the linguistic diversity
Viviane M. de Oliveira, Paulo R. A. Campos, Marcelo A. F. Gomes +1
A simple spatial computer simulation model was recently introduced to study the evolution of the linguistic diversity. The model considers processes of selective geographic coloniz…
